A type of injection molding mold for automotive roof sealing strips

Abstract

This utility model discloses an injection molding mold for automotive roof sealing strips, belonging to the technical field of sealing strip injection molding molds. It includes an upper and lower sealing plate, with multiple coiled limiting screws fixedly connected to the bottom of the upper sealing plate. In this utility model, after injection molding, the upper sealing plate and upper template move upwards to open the mold. Hydraulic cylinder one drives insert nine, insert ten, and accessory three to move backwards. Simultaneously, accessory three and insert one cooperate to move insert one and insert two to the side. Additionally, hydraulic cylinder two drives the transmission column to move outwards. The cooperation between the transmission column and accessory six drives accessory five to move upwards. The cooperation between accessory five and insert five drives insert five, insert four, and insert three to flip upwards, allowing the product to be manually removed from the mold. This enables demolding of complex products, ensuring product molding quality while reducing operator workload and significantly improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of injection molding molds for sealing strips, and more specifically, to an injection molding mold for automotive roof sealing strips. Background Technology

[0002] Sports car roof sealing strips are mainly used to fill the gap between the roof and the side panels of the car body, serving functions such as waterproofing, dustproofing, sound insulation, and decoration. Because sports car roofs often have irregular curved surfaces, the sealing strips need to fit seamlessly with the roof, windows, and other components to meet functional requirements such as waterproofing and sound insulation. Therefore, the sealing strips and injection molding parts have complex shapes and multi-cavity designs, leading to difficulties in demolding and removing parts. Previous mold structures used a multi-core, segmented design, requiring many manual core removal actions, resulting in excessively long production cycles and reduced product production efficiency. To address this, we have proposed a new injection molding mold for automotive roof sealing strips. Utility Model Content
